Feeding of Phytobiotics and Exogenous Protease in Broilers: Comparative Effect on Nutrient Digestibility, Bone Strength and Gut Morphology

In this feeding trial, a total of 500 Cobb-500 broiler (day-old) chickens were randomly assigned to control dietary treatment (basal diet only) or supplemented with crushed seeds coriander (Coriandrum sativum L.), black cumin (Bunium persicum (Boiss.) B. Fedtsch) and ajwain (Carum copticum L.) (at 10 mg/kg each) exogenous protease (30,000 IU/kg), respectively, in order assess the effect diets on nutrient digestibility, bone strength gut morphology. The results indicated that digestibility coefficients crude protein, fat, nitrogen-free extract, calcium phosphorous significantly (p < 0.05) higher protease-treated birds compared control. tibia weight was improved = 0.03) Carum copticum, Coriandrum protease-supplemented birds. Bone length increased fed broilers, while robusticity index decreased all treatments. Villus width Bunium broilers. From findings, it demonstrated shows comparatively better improving quality, ileal villus morphology
